So I just refreshed my facts a bit, was going off memory. So petricola max out at 4-5" and multipunctatus at 6-1/2" inches. They look very similar but the petricola has white edges to its fins where the multi doesn't. There are alot of synodontis catfish out there and all that I have seen have spots and you have to look close to tell the differences. I'm wondering if your cuckoos are petricola and your petricola is multipunctatus.
